PACKING BOX.

Application filed January 7, 1920. Serial No. 850,051.

To all whom it may concm:

Be it known that I, JOHANNES RUDOLPH SURMANN, a citizen of Bremen,residing at Bremen, 156/160, am Wall, Germany, have invented certain newand useful Improvements in Packin Boxes, of which the following is aspeci cation.

The invention is directed to a packing box, constructed of cardboard orthe like, wherein the various sections are so interfolded and associatedas to provide a closed box of unusual strength and durability withoutthe necessity of any fastening for holding the various sectionstogether.

It has heretofore been proposed to manufacture boxes or containers ofcardboard by folding strips or ieces of particular form together, andhas een also proposed to employ cardboard strips laid crosswise forpacking goods. For example, it has been proposedto, take a strip ofcardboard and fold it into five portions at relative right an les, thenplace it atthe joint upon the mi dle panel of a similar cardboard stripalso folded into five portions, and then to sli the ends of the twostrips under the mi dle panel of the first strip to form the box.

In accordance with the present invention, the cardboard strips arefolded into five parts and are disposed at right angles or crosswise,with the middle panels of the two strips in register. The ends are thenfolded around a frame to complete the box. If desired, andas'contemplated, the frame be a strip folded into frame form with theends disconnected and so arranged that such non-connected ends meettogether in the middle of one of the sides of the main cardboardstrips,then the improved box may be constructed with the strips adaptedto be. arranged perfectly flat when not in box forming positions, tofacilitate transportation.

The invention in its preferred form is illustrated in the accompanyingdrawings, in which:

Fig. 1 is a plan of the cardboard strips preferably corrugated ininitial position.

Fig. 2 1s a perspective view of the frame.

Fig. 3 is'a perspective view of the completed box section.

Fig. 4 is a perspective view, showin the use of an additional framestructure, w ereby the box of Fig. 3 is provided with a flange extensionto receive a cover.

The improved box is preferably constructed of cardboard or the like, andprimarily of two substantially identical sections a and b, scored oradapted for folding along the predetermined lines 1, 2, 3, and 4 of eachstrip. The folding is such that between the lines 1 and 3 of each strip,there is presented a panel 5 having a size commensurate with thatdesired for the box, the sections between the lines of fold 3 and 4 andbetween the lines of fold 4 and the free end of each strip arecommensurate with the desired depth of the box. In conjunction with thestrips a and b, the improved box contemplates a frame d made u ofcardboard and folded into rectangular orm commensurate with the desiredsize of box, the meeting ends of this strip being preferably arrangemid-length one side, as at c.

In forming the box, the strips a and b are arranged with the panels 5 inregistry. The frame 41 is laid upon the box overlying the edges of thealigned panels and the projecting sections of the strips are foldedaround the edges of the frame. in an obvious manner. Thus the box shownin Fig. 3 is completed.

If it be desired that a box he formed provided with a cover, it is onlynecessar to duplicate the box formation shown in ig. 3, and to arrangein one of said box sections a strip 7', formed of cardboard and of asize to snugly fit within one of the box sections and project above theupper edge of the same, thus providing a flange to receive the other boxsection, formed as previously described, as a cover. The strip f formingthe flange is also made of an unconnected stri the meeting edges ofwhich are preferab y arranged at one corner of the box section at whichthe flange is positioned, as for example, at 6, Fig. 4.

I claim- 1. A separable cardboard box made u of three strips of cardboard having each f our folding lines, two of which strips beingarranged in super-imposed relation forming a rectangular frame and setupon t bent to a e bottom,

the outer portions of said two first strips being bent around the saidframe so as to 5 form triple closed side walls.

2. A separable card board box made up of three strips of card boardhaving each four foldin lines, rangecl 10 double bottom, and the thirdbein rectangular frame and set upon two of which strips being arinsuper-imposed relation forming a bent to a e bottom,

the outer portions of said two first strips having sue a bight equal tothe width of the said frame and being bent around the sides of the frameso as to form triple 1 closed and fixed side walls.

j In testimony whereof I affix my signature in the presence of twowitnesses.
